Formulation and evaluation of scheduling techniques for control flow graphs

This paper presents a theoretical basis for scheduling approaches based on purely control-flow graphs. This formulation includes a control flow graph model based on a finite discrete-time homogeneous Markov chain suitable to represent complex control structures. A probabilistic finite state machine is introduced to model the resulting schedule and evalute the effectiveness of the scheduling approaches for control flow graphs. The need of such models is imposed by the nature of real time systems in which the control sequence depends on external conditions
